Shorepower Cop

Marinco’s heavy-duty GalvanAlert offers a visual check for AC problems.

Billed as “the world’s only shorepower corrosion detector with reverse polarity indicator” by West Marine, Marinco’s new Galvan-Alert attaches to your existing 30-amp shorepower inlet and power cord and monitors galvanic and stray current corrosion flowing through the green ground wire ground of your shorepower system.
